The shape is a a double helix ! single strand is one side
Answer:
The problems that can be caused by Expansion or Contraction a;long with the solutions are:
Explanation:
- The railway tracks made of steel expand during the summer and contract during the winter. This can cause them to become curved during the summer thereby causing rail derailment.In order to prevent this, an air gap is kept in between the railway lines so that they get the space to expand without getting curved.
- The electric wires linking the telegraph posts are made up of metals and so they expand in the summer and contract in the winter, which can cause them to tear. This is why the wires are loosely fixed so that they can expand and sag in the summer and contract and tighten in the winter.
- Bridges are constructed with joints where some space is maintained to allow the easy expansion and contraction in summer and winter respectively.
The answer is B (400 j) because 10% gets taken off so it would go from 4,000 to 400 then to 40
Answer:
The correct answer is option d. "The phospholipids in this procedure had a shorter average fatty acid tail length than in the original experiment".
Explanation:
One factor that affects the speed at which fluorescent proteins achieve an even distribution is the length of the average fatty acid tails. Cell hybrids are produced by the fusion of two cells, which means that the genomic content of each cell must surpass the cell membrane barrier. The shorter the average fatty acid tails of the phospholipids in the cell membrane are, the faster the cell fusion will occur and the faster the fluorescent proteins will achieve an even distribution.
